I just had a phone call from this company. I stayed on the line for a long time, till someone came on. They asked if I was still involved with stock market I said no and they hung up. Seems like a scam.

Yup, same as the other 2 that have posted here today, dead on the other end, could be collecting live numbers for auto-dialed telemarketing.  I've blocked them with my Shaw phone privacy features.

Constant calls to our house.  No one on the other line.
